2010 Regional Transmission Expansion Plan Report

PJM’s Regional Transmission Expansion Plan (RTEP) identifies transmission system additions and improvements needed to keep electricity flowing to 51 million people throughout 13 states and the District of Columbia. Studies are conducted to test the transmission system against mandatory NERC national standards as well as PJM regional standards.

If reliability criteria violations are identified, then PJM is required to develop and implement solutions to mitigate those violations. New RTEP recommendations are submitted to PJM’s independent Board of Managers (PJM Board) periodically throughout the year to resolve identified reliability criteria violations. Once approved, they become part of PJM’s overall RTEP.

A report is published annually by PJM to convey the results of planning studies throughout the previous calendar year and to explain the rationale behind why transmission system upgrades are needed. The discussion in this document of system drivers, reliability criteria violations and upgrades themselves is for reporting purposes to facilitate greater RTEP understanding.

PJM's 2010 RTEP report, dated February 28, 2011 reflects planned system upgrades approved by PJM’s Board through December 31, 2010. To order an electronic version of the report on CD, please contact PJM Member Relations. Please include the mailing address of where you want your copy sent to along with the number of copies desired in the Comments section of the form. The CD electronic version as well as the full posted report file feature an interactive topical index.

Please note: Preliminary 2011 PJM RTEP process analysis suggests that the need for the PATH line has moved several years beyond 2015. The outlook for a slower economic recovery – reflected in the reduced load growth rates in PJM’s January 2011 published forecast – has led the PJM Board to direct transmission owners to suspend efforts on the PATH line pending a more complete analysis in the 2011 RTEP. Section 5 of this report discusses the PATH suspension.
